Symptoms include fever, chills, headache, muscle aches, and tiredness. Description Ehrlichiosis is a tick-borne disease caused by infection with Ehrlichia bacteria. Ticks are small, blood-sucking arachnids. Although some ticks carry disease-causing organisms, most do not. When an animal or person is bitten by a tick that carries bacteria, the bacteria are passed to that person or animal during the tick's feeding process. It is believed that the tick must remain attached to the person or animal for at least 24 hours to spread the infection. There are two forms of ehrlichiosis in the United States; human monocytic ehrlichiosis and human granulocytic ehrlichiosis. Monocytic ehrlichiosis is caused by Ehrlichia chaffeensis , which is spread by the Lone Star tick, Amblyomma americanum . As of early 1998, about 400 cases of monocytic ehrlichiosis had been reported in 30 states, primarily in the southeastern and south central United States. The bacteria that causes granulocytic ehrlichiosis is not known, but suspected to be either

Article taken from May 2000 Disease Control Newsletter Human Granulocytic Ehrlichiosis in Minnesota Human granulocytic ehrlichiosis (HGE) is a bacterial disease transmitted to humans by Ixodes scapularis (deer tick or black-legged tick), the same tick that transmits Lyme disease. The HGE agent has not been named, but it is similar or identical to two veterinary pathogens (i.e., Ehrlichia equi and Ehrlichia phagocytophila ). The disease was first recognized during 1993 in several patients from Minnesota and western Wisconsin. A human monocytic form of ehrlichiosis caused by Ehrlichia chaffeensis is found throughout much of southeastern and southcentral United States but does not appear to be an important vector-borne disease in Minnesota. Epidemiology of HGE in Minnesota From 1997 to 1999, 82 cases (19 confirmed and 63 probable cases) of HGE were reported in Minnesota. Thirty-six (44%) of those cases occurred in 1999. Two (2%) of the 82 cases were fatalities. Similar to the demographics of Lyme disease in Minnesota, 62% of the HGE cases were male, and most reported likely exposure to infected ticks in the same east-central Minnesota counties where the risk of Lyme disease is greatest ( see map ). The HGE cases ranged in age from 4 to 85 years; the median age (61 years) was older than that of Lyme disease cases (34 years). Peak onset of disease was from May to July (76% of cases), corresponding to the peak activity period for the nymph stage of

National Institute of Allergy and Infectious Diseases and the Office of Rare Diseases Workshop on Human Ehrlichiosis The Division of Microbiology and Infectious Diseases, NIAID with support from the Office of Rare Diseases convened a workshop on "Human Ehrlichiosis" on September 25, 1996, at the Solar Building (Room 1AO4) in Rockville, Maryland. About 20 individuals were invited to the workshop; approximately 25 were in attendance. The agenda for the workshop, as well as copies of abstracts of papers presented by invited speakers all of whom are internationally known experts in the field, are attached. The meeting was considered to be a great success by all who attended. It provided not only a comprehensive summary of the current state of knowledge, but also served to identify the following major gaps in our knowledge of human ehrlichiosis: the need to characterize more fully the clinical symptoms, pathogenesis, and epidemiology of human ehrlichiosis in order to improve diagnosis, the lack of sufficient knowledge concerning the entire spectrum of strains involved in the expression of human ehrlichiosis

Ehrlichiosis What is ehrlichiosis? Ehrlichiosis is a tickborne disease of humans and animals caused by bacteria named Ehrlichia . The bacteria are transmitted by ticks and can infect two different types of white blood cells. The first human case in the U.S. was reported in 1986, in a man exposed to ticks in Arkansas. Who gets ehrlichiosis? Anyone can get ehrlichiosis, although the majority of known cases have been in adults. People who spend time outdoors in tick-infested areas from April until October are at greatest risk for exposure. How is the disease spread? The bacteria are transmitted to humans by the bite of an infected tick, including the deer tick, the dog tick and the Lone Star tick. Ehrlichiosis cannot be spread from person to person. What are the symptoms of ehrlichiosis? The most common symptoms are fever, chills, muscle aches, weakness and headache. Patients also may experience confusion, nausea, vomiting and joint pain. Unlike Lyme disease or Rocky Mountain spotted fever, a rash is not common. Infection usually produces mild to moderately severe illness, with high fever and headache, but may occasionally be life-threatening or even fatal. When do symptoms appear?

Article Ehrlichiosis is an emerging tickborne infectious disease caused by obligate intracellular, gram-negative rickettsia that infect leukocytes. Human monocytic ehrlichiosis (HME) is caused by Ehrlichia chaffeensis and is believed to be transmitted by Amblyomma americanum (the Lone Star tick). Most HME cases have been reported in southeastern and south-central states. During May-July 1994, five cases of serologically confirmed HME were identified among residents of Maryland. All five persons lived near the Chesapeake Bay and had antecedent histories of tick exposure. This report summarizes the clinical and epidemiologic features of these cases and the results of serologic testing at CDC of specimens from Maryland residents with suspected tickborne infection. Serologic testing. The Shore Health Laboratory in eastern Maryland saved frozen aliquots of serum specimens from 91 patients submitted for RMSF serology by physicians practicing on the eastern shore of Maryland during 1993 and 1994. CDC performed IFAs for Rickettsia rickettsii and E. chaffeensis antibodies on these specimens. Of the 12 persons who provided both acute- and convalescent-phase specimens, one was positive for R. rickettsii and two for E. chaffeensis; of the latter two, one had at least an eightfold increase in IFA titer, and the other had titers of 1:256 and 1:512 on serum samples drawn 6 weeks apart. Of the 79 patients with one blood specimen, no samples were positive for R. rickettsii; however, 11 (14%) had titers to E. chaffeensis of greater than or equal to 1:128, which is considered to be consistent with recent infection.

In June 1995, the Westchester County (New York) Department of Health (WCDOH) received reports from physicians who were treating patients for suspected HGE. In response, the WCDOH sent information to all primary-care physicians in Westchester County describing the clinical and laboratory features of ehrlichiosis (fever, myalgia, headache, leukopenia, and thrombocytopenia) and requested that they voluntarily report suspected cases of ehrlichiosis. This report summarizes an investigation by the New York State Department of Health (NYSDOH) and the WCDOH of suspected ehrlichiosis cases and the clinical characteristics of confirmed and probable cases. Of the 23 confirmed cases, 11 had a fourfold rise in antibody titer to E. equi using a polyvalent antihuman conjugate, and 15 had HGE 16S ribosomal DNA detected from acute serum specimens (a positive PCR test). One confirmed case also had characteristic morulae observed in granulocytes on a peripheral blood smear. The six probable cases had single titers greater than or equal to 64 to E. equi. Five case-patients had serologic evidence of E. chaffeensis infection (titer greater than or equal to 64) but all had at least a 10-fold greater titer to E. equi.

Of 10 dogs that were infected, one died acutely and nine progressed into the subclinical phase, (i.e. those who had recovered from the acute infection and were clinically healthy for at least two months). The subclinical phase of the disease was examined over a period of 6 months, during which blood samples were collected on ten different occasions at two to three week intervals. The following results were obtained during the subclinical phase and were compared to examinations made for those parameters before controlled infection of the dogs: - All subclinically infected dogs had high IFA antibody titers to E. canis at a dilution varying from 1:2,560 to 1:20,480.

New York City Department of Health and Mental Hygiene Bureau of Communicable Disease Human Ehrlichiosis What is human ehrlichiosis? Ehrlichiosis is a tick-borne infection caused by bacteria of the genus Ehrlichia. Two types of ehrlichiosis are common in the northeastern United States: granulocytic ehrlichiosis (HGE) and monocytic ehrlichiosis (HME). These diseases are named for the type of white blood cell they most commonly infect. There were three cases of Ehrlichiosis reported among New York City residents in 2001 (rate of 0.04 per 100,000 persons). How is ehrlichiosis spread? Ehrlichiosis is spread by the bite of an infected tick. HGE is transmitted by the blacklegged tick, Ixodes scapularis, while HME is transmitted by the lone star tick, Amblyomma americanum . Neither of these ticks are common in New York City. Blacklegged ticks may become infected with the HGE agent when feeding on mice or possibly deer and elk. The transmission risk to humans is greatest during the spring and summer, when nymphal ticks are in greatest abundance. Adult Ixodes ticks occasionally feed on humans, so infection can occur in fall and winter when adult ticks are abundant. Lone star ticks become infected with the HME agent when feeding on white tailed deer, but only adults of this tick species commonly feed on humans. Adult

Koret School of Veterinary Medicine, Hebrew University of Jerusalem, P.O. Box 12, Rehovot 76100, Israel Introduction Clinical presentation Experimental infection Pathogenesis ... Treatment Summary Canine monocytic ehrlichiosis may be manifested by a wide variety of clinical signs. Therefore clinicians, particularly those practicing in endemic areas, should always consider the possibility of E. canis infection, especially when dogs are admitted with non-specific signs of illness. Owners should be informed of the potential risk of tick-transmitted diseases in general and CME in particular, and should be instructed to treat their pets against ticks on a regular basis. Introduction The etiologic agent of canine monocytic ehrlichiosis (CME), previously known as canine rickettsiosis, canine hemorrhagic fever, tracker dog disease, canine tick typhus, Nairobi bleeding disorder and tropical canine pancytopenia, is the rickettsia Ehrlichia canis (1). It is a small-gram negative, coccoid bacterium that parasitizes circulating monocytes intracytoplasmically in clusters called morulae (2). Ehrlichia canis is mainly transmitted by the brown dog-tick Rhipicephalus sanguineus (3, 4) and has also recently been shown to be transmitted experimentally by the tick Dermacenter variabilis (5). The distribution of CME is related to the distribution of the vector and has been reported to occur in Asia, Africa, Europe and America (6, 7, 8).

Introduction Tick-borne illnesses are caused by infection with a variety of disease-causing pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. Because ticks can harbor more than one disease-causing agent, persons can be infected with more than one pathogen at the same time. While there are several different ticks that carry disease, the one many people are familiar with is Ixodes scapularis, more commonly known as the deer or bear tick in North America. This is the one that causes Lyme disease. Other ticks that transmit B. burgdorferi are the Ixodes dammini and the Ixodes pacificus. Ticks that transmit other diseases include the lone star tick (A. americanum), the dog tick, wood tick, and the Western Black-legged tick.
